FRANK G. GREENE, OIE CLEVELAND, AND CHARLES G. PALMER, OF EAST CLEVELAND, OHIO; SAID PALMER ASSIGNOR TO SAID GREENE.

MECHANISM FOR HANDLING CARS.

To all whom it may concern."

Be it known that we, F RANK C. GREENE and CHARLES Gr. PALMER, both citizens of the United States, residents of Cleveland and East Cleveland, respectively, county of Cuyahoga, and State of Ohio, have invented new and useful Improvements in Mechanism for Handling Cars, of which the following is a specification, the principle of the invention being herein explained and the best mode in which we have contemplated applying that principle, so as to distinguish it from other inventions.

Our invention relates to mechanism for handling cars and particularly to mechanism for handling cars in coal mines and like situations.

Our invention embraces, in conjunction with the usual shaft and tipple structure, novel means for receiving and raising the loaded cars to the surface, there unloading them, thereupon returning them to the shaft, and then lowering them again to the bottom.

The object is to make these operations practically continuous and, so far as it is possible, automatic, thus securing not only an increased efficiency, but a reduction in expense in the running of the plant.

To the accomplishment of this end our invention consists of means hereinafter fully described and particularly set forth in the claims.

The annexed drawings and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawings :Figure 1 represents in side elevation an improved type of cage which forms one of the features of our car handling mechanism, the cage being represented as at rest atthe bottom of the shaft. Fig. 2 represents an end elevation of such cage as it would appear in ascending the shaft. the view being from the left as the cage is shown in Fig. 1. Fig. 3 shows a side elevation of such cage in its position of rest at the top of the shaft. Fig. 4 is an end view of the same, taken from the left in Fig. 3. Figs. 5, 6 and 7'each represent an enlarged view of certain of the details appearing in Figs. 3 and a. Fig. 8 represents the Specification of Letters Patent.

dumping mechanism in position to receive a car preparatory to unloading the same. Fig. 9 shows the same in position to discharge a car. Fig. 10 is a plan view of such dumping mechanism.

The principle of operation which our carhandling mechanism embodies is that of the direct application of power at the fewest possible points in the system, sufficient potential energy being imparted at these points to actuate the mechanism throughout the remainder of the system, which is designed to utilize this energy for the most part automatically. Thus the track T, Fig. 1, in the mine, on which the loaded cars are brought to the shaft opening, is for the latter portion of its length downwardly inclined so as to cause such cars to approach the shaft under the impulse of gravity. The track T, which is designed to receive the empty cars as they are returned to the bottom of the shaft, is similarly inclined but extends in the opposite direction, there being enough difference between the levels of the two tracks where they abut on the shaft to permit a car on the lower track to pass freely beneath the upper track. Suitable switches are of course provided for accommodating the cars on track T and for transferring them therefrom to the main entry track when it is desired. to return them to the rooms of the mine. At the mouth of the shaft a similar arrangement prevails. Track T Fig. 3, is designed to receive the loaded cars when they are raised to the top of the shaft, or to the desired height in the tipple structure, and is inclined downwardly from such point to the dump, the direction of inclination being the same as that of track T. The tipple structure, as also the timbering in the shaft, is designated throughout by the reference letter F. The cars are similarly designated by K. After being dumped the empty car is raised, by means hereinafter fully described, to another track T which is inclined in the opposite direction and abuts on the shaft opening at a distance above that of track T approximately equal to the distance between tracks T and T, at the bottom of the shaft. Aside, then, from the movement of the cars within the mine proper, which does not enter into our system, it is seen that power need be directly applied only in raising the cars from the bottom to the top of the shaft and from track T to track T at the dump.

To raise and lower the cars in the shaft we utilize a cage C, Figs. 2 and 3. This cage has a double deck; the lower deck bears a fixed track C that is inclined. in the same direction as tracks T and T while the upper deck bears a track Cthat is pivoted near one end at 11 and bent at a point about one-third of its length from the opposite end in the manner shown in aforesaid Fig. The etl'ect of such upturned end is that of a stop or bumper with the desirable feature that the car is received without shock or jar. The rails are joined at this end by an angle bar 0, and normally rest on brackets c projecting inwardly from the side members of the cage. .Vhen resting on these brackets the main portion of the track is inclined in a direction opposite to that of track C see Fig. 3. At the bottom of the shaft, however, a projecting frame mem ber F is provided, Fig. 1., that is adapted, as the cage descends and comes to rest, to engage the bar 6" and raise the free end of track C as indicated in the figure referred to, and so incline such track in a direction opposite to that normally occupied and similar to that of track C Track C is provided near its lower end with stops, one on each side, whereby av car resting on such track is preventedfrom run ning off; each of these stops comprises a member 0 keyed on a rock-shaft. a which is disposed parallel with the track. At one end this shaft provided with an inwardly extending weighted arm 0'', the eifcct of which is to normally hold member 0 in position above its appropriate rail so as to intercept a car-wheel moving thereon, Fig. 1. The upturned end of track C serves a similar purpose in connection with such track.

The disposition of mine-tracks T, T, and of cagetracks C, C is such that when the cage is atthe bottom of the shaft, F 1, and the free end of track C upraised in the manner just set forth, the other end of such track will register with track T while the upper end of track C will register with track T. In this situation it will be seen that a car upon cage-track C will be discharged upon track T with an initial speed depending upon the angle of inclination of such track C, which depends in turn upon the height of member F. At the same time a loaded car left free upon track T will move off from such track onto the lower deck of the cage, being retained there by stop-members 0 In like fashion at the top of the shaft, Fig. 8, tipple-tracks T T, are so arranged that the end of cage-track C, Which here occupies its normal position, will register with track T at the same time that the lower end of cage-track C registers with track T It is hence evident that in this position a car resting upon the lower deck of the cage will, upon the removal of stop-members c of its own accord move off onto track T and there proceed until an obstacle is encountered. In like manner a car freely resting upon track T will descend and pass onto the upper deck of the cage, being retained there by the upturned ends of the rails as has already been set forth. To hold the cage in position for such tracks to register as has just been described, pivoted keeps F are provided as shown in Figs. 3 and t. The lower ends of these keeps, at which they are mounted upon rockshafts F lie without the path of travel, of the cage; their upper ends. however, project inwardly so as to be engaged by the sides of the cage as it ascends and be tilted outwardly thereby. Immediately the cage is by, they fall again into their forward position, being restrained from falling too far by chains f, and as the cage is allowed to settle down it rests upon their upper ends. As the. cage thus settles down the central one of these keeps F. Fig. -t, raises the weighted arms a by which stop-members c 011 the lower deck of the cage are operated and thus automatically clears the way for the loaded car to pass onto tipple track T hen it is desired to lower the cage, it is first raised slightly and then such keeps F are tilted back out of its path, a suitable system of leyers 7, connected with shafts F being designed to permit such actuation from any desired station.

To control the movement of empty cars from track T onto the upper deck of the cage we provide an automatically operated stop mechanism, Figs. 3, t3 and 7, that, after one car has passed upon track C, prevents another from. following. This mechanism comprises a pair of stop-members A each keyed on a rock-shaft A. disposed parallel with the track T and normally held in a position to engage a car descending such track, by means of an inwardly extending weighted arm a. This position is indicated in Fig. 6. One end of each rock-shaft A projects a short distance within the mine shaft and has keyed thereon a short horizontally projecting arm or catch a. liitounted along each side of the cage and just below its upper deck are rock-shafts A each bearing a latch 60 adapted to engage the corresponding catch a. To normally retain such latches a in position to engage catches (1/, as also to free them from such engagement, an inwardly extending arm a is mounted on each shaft A and is connected, by means of a rod a with the lower end of a lever A the upper end of which projects above the track C so as to engage the tread of the wheel of a car passing onto the track. The weight of the lever A is so disposed that, augmented by the weight of rod a and arm a it normally suflices to hold the latch a in position to engage the catch. Accordingly as the cage is raised, as has been described in another connection, and is then allowed to descend until it rests upon keeps F, the latch a engages catch a and so rocks shaft A. thereby tilting stop-members A outwardly and permitting the car detained by such stop-members to enter the upper deck of the cage. As the wheels of such car, however, strike the upper ends of levers A it is evident that latches a will be tilted out of engagement with catches a, which, thus freed, allow weighted arms a to raise stopmembers A in time to intercept the next succeeding car on track T The catch a, once it is released, is raised out of reach of the latch a as the latter falls back into its operative position upon the passage of the first car beyond lever A. This lever, it should be remarked, does not serve as a stop for a car upon track C since, in its normal position here occupied, such track inclines in the other direction. When the direction of inclination is changed at the bottom of the shaft, Fig. 1, the car easily passes over the raised end of the lever.

In case there is no empty car on track T to enter the cage, the latch 64 will not be actuated to release catch a. To provide against this contingency an independent releasing device is provided. This consists, Figs. 3 and 5, of a sleeve a loosely mounted upon shaft A and connected with catch a, which is keyed on such shaft, by some flexible means as chains a. Catch a is normally held in position to be engaged by latch a by means of a helical spring a interposed between it and a collar a A bell-crank A is connected with sleeve a", by means of which catch a may be drawn out of engagement with latch a as will be readily understood. Bell-crank A is preferably connected with the system of levers by which keeps F are designed to be operated, so that both may be actuated simultaneously.

It has been shown above how a loaded car is automatically received upon cage at the bottom of the shaft and is automatically discharged upon tipple-track T when the cage is brought to rest at the top of the shaft; also he an empty car is received on the cage at the top of the shaft and discharged therefrom at the shafts bottom. It yet reiains to describe the mechanism whereby such loaded car is dumped and then raised to tipple-track T to be returned to the shaft. Such dumping mechanism, Figs. 8, 9, and 10. comprises essentially a dumping frame D composed of a short section of track. one end of which is adapted to register with the end of tipple-track T and the other end of which is upturned to form a stop cl for a car received thereon from such track T which, it has been noted, is downwardly inclined from the shaft mouth. Such track section D is pivoted at (Z, the line of this pivotal axis being chosen so as to cause the center of gravity of a car resting against stop (Z to lie without it. The weight of such car, it is thus seen, will cause the rear end of the dumping frame to tilt upwardly. Above the free end of the frame and arranged to act as a stop for the same as it swings upwardly, is the end T of upper tipple-track T. This end T is preferably curved in the manner shown in Fig. 8, so as to be in line with the dumping frame when it is inclined at the proper angle to insure the ready discharge of the contents of the car resting thereon. To preventthe frame from dropping back prematurely a catch (Z is provided which is adapted to engage a crossebar d joining the ends of the rails of frame D.

To raise the car, after being emptied, up the inclined frame and on to track T, we provide a pair of endless cables B running over pulleys or sheaves b and joined at suit able intervals by cross rods 6. The disposition of these cables is such that the cross bars I) are adapted to engage the lower end of a car when the frame D occupies its inclined position, Fig. 9, and move it to the desired position on track T As the car thus passes oif frame D and on to track T 3 it depresses a lever arm (Z which, being connected with catch (Z by means of a bar (Z thereupon actuates such catch to release frame D. The center of gravity of such frame, when relieved of the car, being within pivotal axis (Z it falls again to its normal horizontal position.

The oscillatory motion of frame D is controlled by suitable braking means preferably comprising curved swords S attached, one on each side, near the free end of. the frame, and held against friction plates S, Fig. 10, by means of toggle-arms s actuated by a lever S having a weight .9 attached to its outer end. To release the brake a hand-lever S is connected with such toggle-arms s by means of suitable rods and levers 3 whereby the weighted arm S may be raised as will be readily understood. The weighted arm S it will thus appear, auto matically secures the frame in whatever position it may chance to occupy, and the frame is free to move only when hand lever S is actuated. I

To prevent the cars on track T from crowding upon the dumping frame, a stop device is provided whereby only one car at a time is admitted upon such frame, the succeeding car being held until the frame returns to its normal position after the (lumping operation. This stop device comprises a stop-member S pivoted upon a transverse axis a near the end of track T In its vertical position this member extends far enough above the track to intercept a passing car. it rod S connects its lower end with the lower end of an inclined lever arm S fulcrumed at in the tipple structure beneath the dumping frame D and normally projecting far enough above such frame to be engaged by a car resting thereon. Both stop-member S" and arm S are preferably formed of two bars, the end of rod in each case lying between such two bars and being pivotally secured thereto. For reasons that will appear tiis connection should, at. least at one end, he of a resilient character. This we secure by pivotally mounting a crossbead a between the lower ends of the two bars forming member S and then passing rod through an opening in such cross-head and joining it thereto by means of a helical spring .9

Lying beneath the free end of dumping frame D and transversely thereto is a pivoted latch a, adapted to engage a catch a" upon rod lVhen thus engaged said rod is held so as to maintain stop-member S vertica in the normal position of frame D, however, such latch is held outv of engagement with the rod by the pressure of such frame resting upon its outer end.

From the foregoing description of the mechanism. of the dump the manner of its operation is readily perceived. Assuming the dump to be empty and in its normal position, a car proceeding down track T will engage stop-member S, trip the same. and pass upon the dumping frame D until there stopped by upturned ends Z of the frame track. In so doing it will ha e detn'essed lever arm S, Fig. 8, and thus by means of connecting-rod S have raised stop-member S to intercept the following car, the impact of this car against such member being taken up by spring 3 The center of gravity of the frame, with the car upon it. lying without its pivotal axis a, such frame will tilt upward as soon as the operator actuates lever S to relieve the brakes. The free end of the frame accordingly rises until engaged by catch (7 the end of the car being at the same time opened. either manually or by mechanical means not shown, and its contents discharged. The tilting of the frame, it will be seen, relieves the pressure upon arm S whereby the succeeding car would be allowed to move on were it not f r latch a which drops into catch 5" just as arm a is released.

.Vhen the dumping frame is locked in its upper position the car is engaged by the belt arrangement 13 and carried up on to 3 upper tipple-traclt T where gravity carries it toward the shaft. In passing up over the downwardly bent end T of track T 3 such arness which thereupon sinks to its normal position at a rate of speed controlled by the operator through lever As the frame drops into place it raises latch 5 thus releasing stop S so that the next car is then free to enter the dumping frame; whereupon the operation described repeats itself.

Having thus described the structure and operation of the several parts entering into our improved car-handling mechanism, it only remains to correlate such parts by indieating a complete cycle of operation. The loaded cars as they are collected are held on track T, from which position they are allowed to run, one at a time, pon lower deck C of the cage as it rests at the bottom of the shaft. Thereupon the cage is raised to the top of the shaftand as it comes to rest upon keeps F the car is automatically discharged upon lower tip ile-track T along which it proceeds to the dumping frame D. Here it is emptied of its contents in the manner just set forth in detail, and is then raised to the upper tipple-track T 3 which conducts it back to the mouth of the shaft. Here, as soon as the cage is in proper position to receive it, it is taken thereon and lowered again to the bottom where. it is likewise automatically discharged onto track T and is ready to be hauled back into the mine and again loaded. The progress of a car, except for this last stage, is seen to be continuous through the system and for the greater part automatic, an attendant being required. at. three points only: at the bottom of the shaft to release the cars in order to allow them to enter the cage; at the top of the shaft to control the hoisting apparatus; and at the dumping frame to operate the brake.
